Abstract:

Three-dimensional porous materials with bicontinuous open porous structure, large specific surface area, and high electric and thermal conductivities represent a new class of functional materials for a variety of applications. In recent years, we succeeded in constructing 2D graphene into a 3D bicontinuous architecture, leading to the development of 3D nanoporous graphene. Since then, comprehensive studies have been conducted on this new material, ranging from the designable fabrication of 3D nanoporous graphene with tuneable microstructure and physicochemical properties to exploring its wide range of applications for energy conversion and storage, transistor, photodetector, etc. In this talk, I’ll present recent advances in the development of 3D nanoporous graphene for energy applications. The content begins with an overview of this material and its structural and physical features, followed by an introduction to the advanced fabrication techniques that have enabled flexible and precise control over its microstructure and surface chemistry. Subsequently, the applications of 3D nanoporous graphene for electrochemical energy conversions and storage will be discussed.
